Singer Billy Joel, 76, canceled his summer tour due to normal pressure hydrocephalus (NPH), a treatable but often misdiagnosed brain condition. NPH causes fluid buildup in the brain, leading to walking difficulties, cognitive issues, and incontinence, often mistaken for aging. Joel's public announcement raises awareness of NPH, which is diagnosed via CT scan or MRI and treated with a shunt to drain excess fluid. While surgery isn't always necessary, early diagnosis improves outcomes.
